True or False
1) Magnetic fields ONLY exert a force on moving charges.
2) Charges moving with constant velocity produce electromagnetic radiation (light)
3) A stationary negative charge in a downward pointing magnetic field feels an upward pointing force from the field.
4) The double slit experiment is a demonstration of how small particles behave fundamentally differently than macroscopic (large) things.
Homework Answers
1. True.
Magnetic field exert force on moving charges
2. False.
Since accelerating charge only produces electromagnetic radiation. Constant velocity means no acceleration.
3.False.
Since stationary charge doesn't experience magnetic force
4. True
Double slit experiment shows the wave property of small particles. Thus macroscopic particles show wave property thereby behaving fundamentally differently

Force on Moving Charges in a Magnetic Field
Magnets exert forces on other magnets even though they are separated by some distance. Usually the force on a magnet (or piece of magnetized matter) is pictured asthe interaction of that magnet with the magnetic field at its location (the field being generated by other magnets or currents). More fundamentally, theforce arises from the interaction of individual moving charges within a magnet with the local magnetic field. This force is written ,where is the force, is the individual charge (which...
